[0028] The utility model embodiment provides a battery clamp, referring to Figure 1 , the battery clamp includes:

[0029] Two jackets 110 are hingedly connected to each other, and opposite ends of the two jackets 110 are clamping ends 111. The clamping ends 111 of the two jackets 110 can be relatively opened and closed;

[0030] A reset member 120, the reset member 120 acts on the two jackets 110, and is used to provide an elastic force to the two jackets 110;

[0031] Two conductive teeth 130, one conductive tooth 130 is detachably mounted on the clamping end 111 of one jacket 110, and the other conductive tooth 130 is detachably mounted on the clamping end 111 of the other jacket 110, and the two conductive teeth 130 are used to cooperate in clamping the electrode when the clamping ends 111 of the two jackets 110 are closed.

[0032] In the present invention, one of the two jackets 110 is provided with two rotating shafts, and the other jacket 110 is hinged with the other jacket 110 through the two rotating shafts. The opposite ends of the two jackets 110 are clamping ends 111. The two jackets 110 can be pivoted relative to the rotating shafts, and the clamping ends 111 can be relatively opened and closed during the pivoting. The two jackets 110 are provided with a logo area, and a logo mark can be engraved or pasted on the logo area. The logo mark here refers to a specific graphic symbol, text or combination used to represent a company, brand, organization or product. The setting of the logo mark can help consumers quickly identify and recognize the source and manufacturer of the product. The jacket 110 of the battery clamp is the part that the user directly contacts, and it is necessary to ensure the comfort and safety of the user when using it. Among them, the two jackets 110 are made of rubber, and rubber has good insulation properties. When the battery clamp is connected to the electrode of the car battery, the circuit is turned on and the current passes through the conductive clamping teeth 130. The rubber jacket can effectively prevent the current from passing through the jacket 110 and flowing through the user, thereby reducing the risk of electric shock.

[0033] The reset member 120 acts on the two jackets 110 to provide elastic force to the two jackets 110. The reset member 120 is a component that can provide elastic force and can be a compression spring, the two ends of which are respectively connected to the two jackets. When the user applies an external force to the jacket 110, the compression spring is compressed to open the clamping end 111 of the jacket 110 and then clamp it on the electrode of the emergency power supply equipment.

[0034] One of the two conductive teeth 130 is detachably mounted on the clamping end 111 of one jacket 110, and the other conductive tooth 130 is detachably mounted on the clamping end 111 of the other jacket 110. The two conductive teeth 130 are used to cooperate in clamping the electrode when the clamping ends 111 of the two jackets 110 are closed. The two conductive teeth 130 can be made of copper alloy, which has good anti-deformation ability and excellent electrical conductivity. When the conductive teeth 130 are clamped on the electrode of the emergency power supply equipment, a certain clamping force can be maintained, and at the same time, it is ensured that the electric energy of the emergency power supply equipment can be effectively transmitted to the car, so that the car can be started.

[0035] The battery clamp provided by the utility model has two conductive teeth 130 corresponding to the clamping ends 111 of the two clamping sleeves 110. When the conductive teeth 130 on any one of the clamping sleeves 110 are deformed, damaged, or the tooth tips are worn out, it is only necessary to dismantle and replace the deformed, damaged, or worn-out conductive teeth 130 without replacing the battery clamp as a whole. The battery clamp has a long service life and low cost.

[0036] In some embodiments, reference Figure 2 and Figure 3, one of the jacket 110 and the conductive clip 130 installed on the jacket 110 is provided with a clamping hole 112, and the other is correspondingly provided with a clamping column 113 that is clamped and matched with the clamping hole 112. Optionally, the clamping hole 112 and the clamping column 113 are interference-fitted, and the clamping hole 112 can be fixed on the clamping column 113 by applying sufficient external force, which is simple to install and relatively stable; or, the inner side of the clamping hole 112 is provided with an internal thread, and the outer side of the clamping column 113 is provided with an external thread, and the clamping hole 112 and the clamping column 113 are fixed by threaded connection, which is simple to install and convenient to disassemble. Optionally, the jacket 110 is provided with a clamping hole 112, and the conductive clip 130 installed on the jacket 110 is provided with a clamping column 113; or, the jacket 110 is provided with a clamping column 113, and the conductive clip 130 installed on the jacket 110 is provided with a clamping hole 112.

[0037] In some embodiments, a guide surface 114 is provided at the periphery of the opening of the clamping hole 112, and the guide surface 114 is used to guide the clamping column 113 into the clamping hole 112. The guide surface 114 is provided on the side of the clamping hole jacket 110 that contacts the conductive clamping teeth 130. When the clamping hole 112 is installed on the clamping column 113, the guide surface 114 will guide the clamping hole 112 to be quickly and accurately sleeved on the clamping column 113, thereby shortening the assembly time and improving the assembly efficiency. Optionally, the guide surface 114 is an inclined surface; or, the guide surface 114 is an arc surface.

[0038] In some embodiments, the conductive teeth 130 include a front tooth portion 133 and side tooth portions 134 disposed on opposite sides of the front tooth portion 133, and the tooth shape of the side tooth portion 134 is arc-shaped. It can be seen from the conductive teeth 130 described above that there are two conductive teeth 130, so both conductive teeth 130 have a front tooth portion 133 and a side tooth portion 134. Among them, the front tooth portions 133 of the two conductive teeth 130 are in a staggered bite state in the initial state, and the dimensions of the front tooth portions 133 in the length direction are equal. The number of teeth of one front tooth portion 133 is an odd number, and the number of teeth of the other front tooth portion 133 is an even number, so as to ensure that the front tooth portions 133 are staggered bite in the initial state. When the battery clamp is clamped on the electrode of the emergency power supply equipment, the tooth tips of the front tooth portions 133 will not be at the same contact point, which can reduce the load on the contact point of the tooth tips of the front tooth portions 133, thereby reducing The damage to the tooth tip of the front tooth portion 133 is reduced; the tooth shape of the side tooth portion 134 arranged on the opposite sides of the front tooth portion 133 is arc-shaped, and the side tooth portions 134 of the two conductive clamping teeth 130 are arranged oppositely. The arc-shaped side tooth portion 134 is an arc-shaped arc that is recessed on the side away from each other of the two conductive clamping teeth 130. The arc-shaped side tooth portion 134 can adapt to electrodes of larger sizes, and the arc-shaped tooth portion 134 can form a wider range of contact points on the electrode contact surface, thereby ensuring that the electrode can obtain sufficient clamping force. In addition, when the arc-shaped side tooth portion 134 is clamped on the electrode of the car battery compared to the straight side tooth portion 134, the opening of the front tooth portion 133 will be smaller, and even if the battery clamp is subjected to a certain external force after the clamping is completed, it will not fall off easily.

[0039] In some embodiments, an end of the conductive clamp 130 away from the front tooth portion 133 is provided with an electrical connection portion 135 for connecting a wire. It can be seen from the above-mentioned conductive clamp 130 that there are two conductive clamps 130, one end of the wire is connected to the emergency power supply equipment, and optionally, when the wire is a single-core wire, the other end is welded to the electrical connection portion 135 of one of the wire conductive clamps 130; or, when the wire is a multi-core wire, the other end is welded to the electrical connection portion 135 of two wire conductive clamps 130. When the car battery is low or the engine cannot be started, the positive and negative battery clamps are clamped on the positive and negative poles of the car battery respectively, the circuit is turned on, and the electric energy of the emergency power supply equipment is transmitted to the battery of the car, so that the car can start normally.

[0040] In some embodiments, the electrical connection portion 135 is provided with a limiting groove 136 for accommodating and limiting the wire. It can be seen from the electrical connection portion 135 described above that the other end of the wire is welded to the electrical connection portion 135. When the electrical connection portion 135 is provided with the limiting groove 136, the other end of the wire is welded to the inner side wall of the limiting groove 136 and is clamped in the limiting groove 136. The limiting groove 136 clamps one end of the wire so that it will not shake significantly, thereby preventing the wire welding end from breaking due to significant shaking.

[0041] In some embodiments, the other end of the two jackets 110 is a gripping end 115, each gripping end 115 is provided with a limit plate 116, the reset member 120 is a torsion spring, the torsion spring is installed between the two jackets 110, one end of the torsion spring abuts against the limit plate 116 at the gripping end 115 of one jacket 110, and the other end abuts against the limit plate 116 at the gripping end 115 of the other jacket 110. When the user applies an external force to the two gripping ends 115, the two ends of the torsion spring abut against the two limit plates 116 respectively, and the limit plates 116 can prevent the torsion spring from sliding off the jacket 110, so that the jacket 110 can be twisted by the torsion spring, the gripping end 111 of the jacket 110 is opened, and then the conductive clamping teeth 130 are opened, and then clamped on the electrode of the car battery.

[0042] In some embodiments, at least one of the limiting plates 116 at the gripping ends 115 of the two clamps 110 is provided with a groove 117, and the groove 117 is used to position the wire connected to the conductive clamping teeth 130. The size of the wire connected to the conductive clamping teeth 130 is adapted to the size of the groove 117, and the wire can be just stuck in the groove 117, and will not swing around the clamping teeth 110 at will, causing inconvenience to the user. In addition, the end of the torsion spring described above is bent to form a U-shaped groove, the opening of the U-shaped groove is opposite to the groove 117, and forms an elliptical hole with the groove 117. The wire is firmly placed in the hole, which can further limit the position of the wire connected to the conductive clamping teeth 130.

[0043] In some embodiments, reference Figure 3 The gripping end 115 is provided with a gripping portion, which is arched and provided with an anti-skid groove 118, and the anti-skid groove 118 is provided on the side away from the torsion spring. When the user holds the battery clamp, the palm is in an arc-shaped state, and the gripping portion of the arched gripping end 115 is in an arc shape, which can better fit the palm, and the contact area between the palm and the gripping portion of the gripping end 115 is larger, which makes the user more labor-saving when operating; the gripping portion of the gripping end 115 is provided with an anti-skid groove 118, wherein the anti-skid groove 118 can be provided in a variety of ways, optionally, a plurality of anti-skid grooves 118 are provided along a length direction perpendicular to the jacket 110, and the plurality of anti-skid grooves 110 are arranged at intervals; or, a plurality of anti-skid grooves 118 are provided along a length direction parallel to the jacket 110, and the plurality of anti-skid grooves 118 are arranged at intervals. An anti-slip groove 118 is provided on the gripping portion of the gripping end 115 , so that when the user holds the gripping portion, the friction between the gripping portion and the user's hand can be increased, and the battery clamp will not slip out of the hand easily.

[0044] In some embodiments, at least one of the two jackets 110 is provided with a polarity mark 119 located at the clamping end 111. There are two battery clamps when in use, one of which is a positive battery clamp and the other is a negative battery clamp. In order to correctly distinguish the positive battery clamp from the negative battery clamp, a polarity mark 119 is provided on at least one of the two jackets 110. For example, the positive battery clamp is indicated by a "+" polarity mark 119, and the negative battery clamp is indicated by a "-" polarity mark 119. The user can quickly distinguish the polarity of the battery clamp according to the polarity mark 119, and clamp the battery clamp on the corresponding electrode, saving operation time and reducing the possibility of incorrect clamping.
